Applications
Build multiple layers of safety rather than relying on single protection. Diversify across assets. Maintain cash reserves. Avoid excessive leverage. Don't concentrate in single sector. Each layer reduces catastrophic risk. Redundancy is expensive until it saves you.
Seek asymmetric opportunities where downside is clearly bounded but upside is open-ended. Early-stage startups fit this profile if you control position size. So do out-of-the-money options on mispriced assets. So do relationships and learning. Look for positive optionality.
Use leverage cautiously with pessimistic assumptions about how wrong things could go. Leverage amplifies returns but also accelerates destruction. If you use it, assume worse outcomes than seem likely. Ask: "if everything goes wrong, can I survive?" If answer is no, you're overleveraged.
Focus on avoiding unforced errors rather than making spectacular plays. In investing as in tennis, most money is lost through mistakes, not lack of brilliance. Compound steadily by not losing rather than trying to hit home runs. Survival first, then prosperity.
